Referring to fig. 2, in an embodiment, a method for controlling laser power includes the steps of:
step S10, when receiving an instruction for starting a laser generator, acquiring target laser power and initial laser power, wherein the initial laser power is smaller than the target laser power;
in this embodiment, when receiving an instruction to start the laser generator, the target laser power that the laser generator needs to reach in a normal state and the initial laser power when the laser is just started can be obtained, because when the laser performs cutting, welding, marking and other processes, the medium of the deflected laser path such as the laser generator and the vibrating mirror is generally started at the same time, and the actual laser effect of the medium of the deflected laser path such as the vibrating mirror starts to move is greatly different from the ideal effect, in this embodiment, the laser generator is actually started according to the initial laser power that is smaller than the target laser power while the medium of the deflected laser path such as the vibrating mirror starts to move, so that the laser generator is sequentially controlled by at least two laser powers, and the actual laser effect of the laser generator brought by the laser power at each stage can be closer to the ideal effect corresponding to the target laser power, the laser effect of cutting, welding, marking and other treatments by using a laser generator is improved.
Optionally, as shown in fig. 5, if the lasers of different types are all started according to the target laser power, since the medium of the deflected laser path such as the vibrating mirror starts to operate from a static state and gradually accelerates to the target movement rate when the laser generator is just started, the medium of the deflected laser path such as the vibrating mirror is in an accelerated operation state in the process, the laser pulse points are too dense when the laser generator is just started, the actual laser effect is too strong, and the laser pulses are gradually dispersed and stabilized near the ideal effect corresponding to the target laser power as the movement rate of the medium of the deflected laser path such as the vibrating mirror gradually increases; when the laser generator is about to be closed, the medium of the deflected laser path such as the vibrating mirror begins to be gradually reduced from the target movement rate to zero, namely, in a static state, and the medium of the deflected laser path such as the vibrating mirror is in a speed reduction running state in the process, so that the actual laser effect when the laser generator is about to be closed is gradually increased, and the actual laser effect is too strong.
Alternatively, the target laser power may be a laser power set by an operator in advance, and the target laser power is a laser power that the operator wants the laser generator to actually reach.
Step S20, controlling the laser generator to start according to the initial laser power;
in this embodiment, after the target laser and the initial laser power are obtained, the laser generator is controlled to start according to the initial laser power, so that the laser generator starts to emit laser according to the initial laser power. Because the initial laser power is smaller than the target laser power, the actual laser effect of the laser generator during the initial starting can be correspondingly reduced through the value of the initial laser power, and the actual laser effect of the laser generator during the initial starting is closer to the ideal effect corresponding to the target laser power.
And step S30, when the current operation time of the laser generator reaches a preset time, adjusting the current laser power of the laser generator to the target laser power.
In this embodiment, after laser generator starts according to initial laser power, record this time of continuing operation of laser generator and be long, reach when the length of operation and predetermine the length of time, consider that the medium in the deflected laser path such as galvanometer has stabilized and carry out uniform motion at target motion rate, laser generator's actual laser effect can not produce the error because of the acceleration or the deceleration motion of the medium in deflected laser path such as galvanometer, can be with laser generator's current laser power regulation for target laser power, after adjusting laser generator's current laser power for target laser power, laser generator's actual laser effect is also the same with the ideal effect that target laser power corresponds. That is, the medium of the deflected laser path such as the galvanometer includes an acceleration motion stage (the AB stage in fig. 5-7), a uniform motion stage (the BC stage in fig. 5-7), and a deceleration motion state (the CD stage in fig. 5-7), where the acceleration motion stage is to control the laser generator to start according to the initial laser power, and the uniform motion stage is to control the laser generator to operate according to the target laser power.
Optionally, since the durations (AB segments in fig. 5 to 7) of the accelerated motions of the medium deflecting the laser path such as the vibrating mirror may be different when the different types of laser generators are just started, the correspondence between the type corresponding to the laser and the preset duration may be preset, so as to determine the corresponding preset duration according to the type of the laser generator to be started. Alternatively, the preset time period may be determined according to the duration of the medium acceleration movement phase of the deflected laser path such as a galvanometer.
Alternatively, as shown in fig. 6 and 7, in the acceleration phase (segment AB in fig. 6 and 7) of the medium deflecting the laser path such as the galvanometer, the laser generator may gradually increase the laser power from the initial laser power to the target laser power according to the laser power control shown in fig. 6, or maintain the initial laser power according to the laser power control shown in fig. 7. Similarly, as shown in fig. 6 and 7, in the deceleration movement phase (the CD section in fig. 6 and 7) of the medium deflecting the laser path by the vibrating mirror and the like, the laser generator may gradually decrease the laser power from the target laser power according to the laser power control shown in fig. 6, or may maintain the ending laser power smaller than the target laser power according to the laser power control shown in fig. 7, that is, at a preset time point before turning off the laser generator, the current laser power of the laser generator is adjusted to the ending laser power, so that the actual laser effect of the laser generator may be closer to the ideal effect corresponding to the target laser power in the deceleration movement phase of the medium deflecting the laser path by the vibrating mirror and the like. The preset time point before the laser generator is closed can be determined according to the time point corresponding to the closing of the laser generator and the set time length, the set time length is similar to the preset time length in an obtaining mode, and the calculation mode of the ending laser power is similar to the initial laser power.
In the technical scheme disclosed in this embodiment, through just starting stage at laser generator, start according to the initial laser power that is less than target laser power for actual laser effect when the laser instrument just started weakens, and the actual laser effect of laser generator just starting stage can be more close to the ideal laser effect that target laser power corresponds, has improved the effect of handling such as cutting, welding and marking when laser generator just started.
In another embodiment, as shown in fig. 3, on the basis of the embodiment shown in fig. 2, the step of obtaining the target laser power and the initial laser power in step S10 includes:
step S11, acquiring the target laser power corresponding to the instruction for starting the laser generator;
in this embodiment, the instruction of starting laser generator can be triggered by operating personnel or the host computer that operating personnel belongs to, and the instruction of starting laser generator can correspond there is target laser power, and the laser power that the ideal effect that target laser power reaches for actual need laser generator corresponds.
And step S12, acquiring the initial laser power according to the target laser power.
In the present embodiment, when the initial laser power is determined based on the target laser power, the initial laser power may be determined based on a correspondence between the target laser power and the initial laser power.
Optionally, the corresponding relationship between the target laser power and the initial laser power includes a preset proportionality coefficient between the target laser power and the initial laser power, and after the target laser power is obtained, a product of the target laser power and the preset proportionality coefficient is used as the initial laser power (as shown in fig. 6 or fig. 7).
Optionally, as shown in fig. 6, the preset scaling factor is generally 0.5, so that the initial laser power is half of the target laser power, and the laser effect when the laser generator is just started is closer to the ideal effect.
Optionally, when the initial laser power is obtained according to the target laser power, the initial laser power corresponding to the target laser power may also be manually set by an operator according to experience.
In the technical scheme disclosed in this embodiment, the target laser power corresponding to the instruction for starting the laser generator is obtained, and the initial laser power is obtained according to the target laser power, so that when the laser generator is started according to the initial laser power, the actual laser effect of the laser generator is closer to the ideal effect corresponding to the target laser power, and the laser effect error caused by the non-uniform motion of the medium of the deflected laser path such as a vibrating mirror is compensated.
In yet another embodiment, as shown in fig. 4, on the basis of the embodiment shown in fig. 2 or fig. 3, before the step S20, the method further includes:
step S40, determining a preset power adjustment period;
in this embodiment, before controlling the laser generator to start according to the initial laser power, a preset power adjustment period may be obtained, so that the actual laser effect of the laser generator may be always close to the ideal effect corresponding to the target laser power during the non-uniform motion of the medium deflecting the laser path, such as the galvanometer, through the gradual adjustment of the laser power at the just-starting stage of the laser generator (as shown in fig. 6).
Optionally, the preset power adjustment period is a time interval of power adjustment when the laser generator is just started.
Step S50, determining the power adjustment times according to the preset duration and the preset power adjustment period;
in this embodiment, the preset duration is the duration of the acceleration phase of the medium in the deflected laser path such as the vibrating mirror (segment AB in fig. 5-7), and the power adjustment times can be obtained by dividing the preset duration by the preset power adjustment period, where the power adjustment times are the power adjustment times required by the laser generator when the medium in the deflected laser path such as the vibrating mirror enters the uniform motion state from the static state.
Optionally, since the durations of the medium acceleration movement phases of the deflected laser paths such as the galvanometer may be different when the laser generators of different types are just started, the corresponding relationship between the type corresponding to the laser and the preset duration may be preset, so as to determine the corresponding preset duration according to the type of the laser generator to be started. Alternatively, the preset time period may be determined according to the duration of the medium acceleration movement phase of the deflected laser path such as a galvanometer.
Step S60, determining a plurality of laser power values according to the target laser power and the power adjustment times, where the plurality of laser power values are all not equal, and are all greater than the initial laser power and all less than the target laser power.
In this embodiment, in the process that the medium of the deflected laser path such as the galvanometer enters a uniform motion state from a stationary state according to the target laser power and the initial laser power, the laser power adjustment amplitude required by the laser generator may be determined, and the laser power adjustment amplitude is divided by the power adjustment times, that is, the difference between two adjacent laser power values in the plurality of laser power values.
Optionally, between the steps S20 and S30, the current laser power of the laser generator may be sequentially increased according to a plurality of laser power values according to a preset power adjustment period, that is, the current laser power of the laser generator may be adjusted once every preset power adjustment period, after the laser generator is started according to the initial laser power, the current laser power of the laser generator may be adjusted to a minimum value of the plurality of laser power values when the current laser power of the laser generator is adjusted for the first time, the current laser power of the laser generator may be adjusted to a second minimum value of the plurality of laser power values when the current laser power of the laser generator is adjusted for the second time, until the current laser power of the laser generator is adjusted to a maximum value of the plurality of laser power values, so that the current laser power of the laser generator may be adjusted to the target laser power just when the current operation time of the laser generator reaches the preset time, so that the actual laser effect of the laser generator can always approach the ideal effect corresponding to the target laser power (as shown in fig. 6).
In the technical scheme disclosed in this embodiment, a preset power adjustment period is determined, the number of times of power adjustment is determined according to a preset duration and the preset power adjustment period, and a plurality of laser power values are determined according to the target laser power and the number of times of power adjustment, so that the actual laser effect can be always close to the ideal effect corresponding to the target laser power, and the effects of processing such as cutting, welding, marking and the like when the laser generator is just started are improved.
